What are luminous materials?

Luminescent materials (or phosphors), mostly are solid inorganic materials consisting of a host lattice, usually intentionally doped (Fig. 1). … In the latter kind of applications, luminescent materials are excited by photons with high energy, and part of the excitation energy is used to create visible light.

Is a mirror luminous?

What is in a shadow?

A shadow is a dark area where light from a light source is blocked by an opaque object. It occupies all of the three-dimensional volume behind an object with light in front of it. The cross section of a shadow is a two-dimensional silhouette, or a reverse projection of the object blocking the light.

How do you see light?

When light hits the retina (a light-sensitive layer of tissue at the back of the eye), special cells called photoreceptors turn the light into electrical signals. These electrical signals travel from the retina through the optic nerve to the brain. Then the brain turns the signals into the images you see.
